Eric,
I would never normally rely on my peripheral memory, but I think that I
remember some pre 1960 Morgans that had 15 " wheels came with 5.20 X 15
or 5.60X 15 tires. Seems that a 5.60 is about a 150. I know the sizes
we use now are much wider than those originally furnished. This does not
seem to effect 4/4's so it may just be one of those little annoyances
that +4 drivers have to live with.
